[0015]
The present invention will be illustrated by the following examples, but the present invention is not limited thereto.
[0016]
Example 1
340.3 g of an aqueous solution containing 204.2 g (2 mol) of 2,2-dimethoxyethanal was stirred for about 30 minutes or more while maintaining a temperature of about 20 ° C. by ethanal cooling to give 50 g (1 mol) of hydrazine. Introduce into hydrate. Once the introduction is complete, 5.3 g (50 mmol) of anhydrous sodium carbonate are added to the reaction medium and then left at room temperature for 16 hours with stirring. The expected product crystallizes spontaneously from the reaction medium, which is isolated by filtration, then washed by pasting with ice-cold water and finally dried under reduced pressure to constant weight. 2,2-Dimethoxyacetaldehyde azine is thus obtained in the form of colorless crystals having a melting point of 56.5 ± 2 ° C.
[0017]
[Table 1]
[0018]
Example 2
Example 1 is reproduced by adding sodium carbonate to the hydrazine hydrate before introducing the aqueous solution of 2,2-dimethoxyethanal. Thus pure 2,2-dimethoxyacetaldehyde-azine is obtained in excellent yield.

(Reference J. G ERICKSON et al., J. Amer. Chem. Soc., 77 , 6640-6664 (1955), boiling point = 139.5 ° C.).
